Outline of Final Research Achievements

When a city is hit by a huge disaster, activities and functions of the city necessary for people are lost and damaged. Total loss of the disaster is not only determined by the direct damage but also by recovering speed. The aim of this analysis is to extract spatio-temporal patterns in a city during a disaster recovery process based on aggregated positioning data of mobile phones. In this analysis, we classified activities and functions decreased through spatial patterns of population distribution during a disaster recovery process through a factor analysis, and confirmed difference in recovering speed. Moreover, we suggested that each spatial pattern is related to the spatial pattern in normal time.
